Hey Cedric,
I just ran the Churn-Member-Relative-Chart and Churn-Member-Relative-Chart
for hacky2004-all from Jan 2, 2005 to the current week (see the bottom of
this email). And there are some really strange results. I have some
outrageous Code Churn around 400,000 to 500,000 lines of code compared to
the rest of the hacky2004-all developers, who seem to average in the tens
of thousands. Is that a bug? Or am I really that good? :)
Haha.. Ok, I just spent a little more time figuring why the heck I have so
much Churn. It turns out that I commit HTML documents for documentation
that lives in hackyPRI. These HTML doc files are rather large. It turns out
that I have to change the Parameters values to "**/**.java, true", to get
the churn on java code. After fixing that, Christoph (with ~61K Absolute
Churn and ~21K Relative Churn) seems to be doubling almost everyone else's
churn numbers. Anyway, remember to use "**/**.java" on the telemetry wall
for Churn Telemetry Streams.
A couple more issues:
- in the analysis Telemetry Chart Analysis, is the Parameter Values
selector going to allow a default parameters by leaving this text field
blank? Currently, I have to type in something. Often, it is a little
difficult to guess what Parameters are needed. Especially for parameters
like "mode". The error messages help. But, it usually takes me a couple of
guesses to correctly enter in complex parameters (mode, filePattern,
isCummulative). Furthermore, I'm not sure that a non-csdl member knows what
they have to type in for a filePattern or mode parameter. For example, I
tend to enter in "**.java", which is wrong, the correct string is
"**/**.java". It would be interesting to see how many times Hackystat users
executed the Telemetry analyses.
- it is a little difficult to track down the descriptions of these Reports,
Charts, Streams, and Reducers. If I'm correct the only Telemetry "thing"
that has a description is the Reducer. So, what I had to do to figure out
what a Report was made of (from a top down approach) was go to the
Telemetry Management page for the Reports, Charts, Streams, and Reducers
reading the Names and Definitions. Not to mention, that a Report can
consist of one-to -many Charts, a Chart can consist of one-to-many Streams,
etc.. Even for me (a person that knows about Telemetry Reducers,
Streams, Charts, Reports), the way the information is presented made it
hard for me to understand what I'm seeing and how it was calculated.
Management of the Telemetry (primarily for the administrator) is good in a
bottom-up fashion, like what you have in the Telemetry Management
preferences. But, for a user to understand the results its probably better
presented in a top-down fashion. Another command that shows the underlying
telemetry pieces for a given Report, Chart, and Stream would be a useful
addition. For example, the use could select "DevelopmentProgressReport "
then get a listing of the Charts, Streams, and Reducers (including
descriptions) that were used to build the Report.
Furthermore, understanding telemetry has the disadvantage of being dynamic,
because other traditional commands can provide the "more" documentation
string to explain the analysis.
- what ever happened to the Standard Deviation lines?
thanks, aaron
